⚠ Under reviewReason CLI native binary for win32-arm64
AI Security Review
scanned 3d ago · by lpm-firewall-aiThe package manifest has no lifecycle scripts, and the inspected JavaScript shows sandbox-related command handling rather than a verified attack. The required native executable analysis is materially limited, so its behavior cannot be resolved from available evidence.
Static reason
One or more suspicious static signals were detected.; source matched previously finalized malicious package; routed for review; source fingerprint signature matched known malicious package; routed for review
Trigger
Use of the Windows ARM64 CLI executable; its precise activation path is unresolved.
Impact
Unknown; no attack impact is confirmed from the inspected source.
Mechanism
The offline analysis identifies the executable as a PE containing candidate embedded source, but cannot establish which code is reachable or exclude other native behavior.
AI rationale
The package manifest has no lifecycle scripts, and the inspected JavaScript shows sandbox-related command handling rather than a verified attack. The required native executable analysis is materially limited, so its behavior cannot be resolved from available evidence.
Evidence
bin/reason.exe.lpm-inspection-BhCXnK/0-22035807627c.txtbin/runtime/srt/sandbox-runtime.mjs
Decision evidence
public snapshotAI called this Manual Review at 84.0% confidence as Unknown with medium false-positive risk.
AI review observations
- package.json describes a Windows ARM64 CLI package containing bin files.
- The analysis of bin/reason.exe is limited to bounded embedded source windows and says it cannot establish loader reachability or rule out other native behavior.
- The bundled sandbox runtime includes a command wrapper with configurable network restrictions, but its relationship to the executable’s behavior is unresolved.
Evidence against
- package.json declares no lifecycle scripts.
- The inspected JavaScript describes sandbox restrictions around a requested command; this alone does not establish malicious behavior.
